What is the time difference between London and Hong Kong?

Hong Kong (HKT, UTC+8) is 8 hours ahead of London in winter (GMT, UTC+0) and 7 hours ahead in summer (BST, UTC+1). Hong Kong does not observe Daylight Saving Time, so the offset changes only when the UK shifts its clocks in spring and autumn.

Does Hong Kong observe Daylight Saving Time?

No. Hong Kong abolished DST in 1979 and has stayed on HKT (UTC+8) ever since. Only London shifts its clocks, which is why the London-Hong Kong gap alternates between 8 and 7 hours.

When does the offset change from 8 to 7 hours?

The UK moves clocks forward on the last Sunday in March at 01:00 GMT, entering BST (UTC+1). At that point Hong Kong goes from 8 hours ahead to 7 hours ahead. The gap returns to 8 hours on the last Sunday in October at 02:00 BST when the UK reverts to GMT.

What are the best meeting times for London and Hong Kong?

In winter (GMT), when London is at 09:00 it is 17:00 in Hong Kong — workable for both sides. In summer (BST), when London is at 09:00 it is 16:00 in HK, giving a slightly better overlap. Aim for 09:00–11:00 London time to catch HK before end of day.

Is this tool accurate for scheduling?

Yes. It uses the IANA timezone database embedded in your browser — the same source used by operating systems and calendar apps worldwide. Accuracy depends on your device clock being synchronized via NTP, which most devices do automatically.

HKT stands for Hong Kong Time. It is UTC+8, used across Hong Kong year-round. There is no Hong Kong Daylight Saving Time because HK has not observed DST since 1979.

Summary

This tool displays the live current time in both London (Europe/London — GMT in winter, BST in summer) and Hong Kong (Asia/Hong_Kong — HKT, UTC+8 year-round, no DST) side by side. Hong Kong does not observe Daylight Saving Time, so the offset between the two cities shifts twice a year: 8 hours ahead of London in winter (GMT) and 7 hours ahead in summer (BST). Use this tool to schedule calls with Hong Kong, coordinate remote teams across the UK and Asia, or check whether HK colleagues are still at work.

How it works

Your browser reads the current moment from your device clock.
It converts that moment to Europe/London time using the IANA timezone database built into modern browsers.
The same moment is converted to Asia/Hong_Kong time (HKT, UTC+8).
The UTC offsets of both cities are compared to calculate the exact hour difference.
All three values — London time, Hong Kong time, and the offset — refresh every second.
When London switches between GMT and BST, the displayed offset adjusts automatically from +8 to +7 hours.
